Last time the wife was out it dropped into the 20's and the fuel supply from the 20lb tank outside ceased. The heater turned off and I couldn't get it re lit without having to switch to the small green tanks

You are technically right but on the practice side Propane liquid gives off vapor down to -44 F, so your 10 F night isn't even close. It freezes somewhere around -300 F.

One thing to keep in mind is the lowered pressure you will have in the tank as it gets colder though, so if it is not turned on before it gets cold, and you just throw the valve open, you may have a high flow preventer that will close off the supply. Open the tank slowly.

We've frozen the valves and lines on a couple of tanks before. A buddy has a 60k (I think, might be 100k) btu heater. In order to get it to put out that much heat, it needs a lot of gas and so it has to run without a regulator. As a gas expands, it absorbs heat from its surroundings. It will quickly freeze a valve and the lines. He had to switch to a large portable tank because the small ones kept freezing up and restricting gas flow. You can put a small tank in a bucket of water and drop warm beer cans in the water. Run a high btu heater off it and it will get your beer cold in a couple of minutes.
